Description

  • The present invention relates to a terminal and a computer for operating with a virtual data processing arrangement, the arrangement for virtual data processing and a method for virtual data processing.
  • In information technology, IT, virtualization concepts are often used, especially in companies, to ensure the high availability of applications. In virtualization, the architecture of an IT infrastructure is based on a central system that centralizes physical resources such as memory, computing power, operating system or applications and provides users. With the help of virtualization, physical resources are abstracted. From the point of view of a user, these resources are faked because they are not actually present at his workplace. However, they are usable like real components. The data is thus processed virtually by remote access to a server.
  • Virtualization concepts differ based on the physical layer on which they are based. This can be, for example, the hardware of a central computer, called server, the operating system or the storage subsystem. Accordingly, a distinction is made between so-called fat clients and thin clients on the part of the user, depending on how much computing power a computer at the user's workplace provides locally and how much computing power is obtained from the server. The common goals of all virtualization concepts are a better use of resources, an easier administration and operation as well as an associated cost saving.
  • The virtualization underlying this application is the so-called desktop virtualization. The complete software, that is the operating system, applications and also the user-replicated workstation of a user, the so-called desktop, runs on a remote server. The devices present at his workstation are therefore used by a user mainly for inputting and outputting data.
  • In currently available desktop virtualization solutions, a number of separate devices, such as an output device, that is, a display, and a connection unit to the server, each with its own power supply, are connected and connected by cable on the user's side. This complicates installation and maintenance, complicates operation and increases the susceptibility to errors.
  • An object to be solved is therefore to improve and simplify virtual data processing, in particular in the area of desktop virtualization.
  • The object is solved by the subject matters of claims 1, 11, 14 and 15. Further developments and refinements are in each case subject of the dependent claims.
  • In one embodiment, a terminal for operation with a virtual data processing arrangement comprises a controller, a virtualization interface, a display, an adaptation unit, a communication unit and a power supply. The controller is coupled to the virtualization interface, the matching unit, the communication unit and the power supply. The virtualization interface is suitable for accessing data processing resources. The display is coupled to the virtualization interface via the adaptation unit and is designed to display information. The communication unit is additionally coupled to the virtualization interface. The power supply is configured to provide power to operate the terminal. The controller, the power supply, the matching unit, the virtualization interface and the communication unit are integrated in a housing of the display.
  • When the terminal is turned on, the controller, the virtualization interface, the matching unit, the display, the communication unit and the power supply are turned on. The communication unit establishes a connection with the arrangement for virtual data processing. An incoming data stream is displayed on the display by means of a visualization interface and adaptation unit. The adaptation unit converts the video signals provided by the arrangement into a video signal format that is used by the display. The user uses the hardware and software resources provided by the device in the form of a virtual desktop.
  • The fact that all components of the terminal are integrated in one housing simplifies the operation and reduces the susceptibility to errors due to the reduced cables. Furthermore, this leads to a minimalization of the terminal. Installation, maintenance and replacement of end devices is simplified.
  • The display comprises in particular a liquid crystal display, a so-called LC display. The adaptation unit is also referred to as a scaler. The power supply is also called power supply.
  • In a further embodiment, the communication unit has a split device, which is coupled to the power supply and comprises a connection for supplying energy and for exchanging data.
  • The splitter separates power supplied from the virtual data processing device from input data. The energy gained in this way is supplied to the energy supply. The data is forwarded to the virtualization interface.
  • Advantageously, the terminal thus requires only one connection cable, namely that for the split device, in order to connect the terminal to the arrangement for virtual data processing. This simplifies and speeds up the installation of the terminal. As a result, the mean time between failures, mean time between failure, MTBF, is increased.
  • One possible implementation is based on the use of Power over Ethernet, for example according to the IEEE standard 802.3 af in which both power supply and data exchange via the network cable. The split device is then called a splitter. Another implementation option is the use of Powerline LAN. Both power supply and network application are made via the 220 V power cable.
  • In an alternative embodiment, the communication unit has an interface for wireless data transmission. Furthermore, a connection coupled to the power supply is provided for supplying energy.
  • The data provided by the device is fed to the virtualization interface via the wireless data communication interface. The supply of energy is via a 220 V connection to the power grid.
  • Again, the terminal is only connected via a connection cable, namely the power cable, with the infrastructure, so the arrangement for virtual data processing.
  • The interface for wireless data processing comprises in particular a wireless LAN, WLAN interface, for example according to one of IEEE 802.11 x standards , This is designed as an access point.
  • In a further development, the controller has a drive element for the energy supply, which is set up to regulate a power supply of the terminal as a function of a respective operating state of the terminal.
  • All components of the terminal, in particular control, virtualization interface, display, matching unit and communication unit are powered by means of the driver and the power supply using only one power supply. The drive realized in conjunction with the power supply integrated power management of all components of the terminal. In particular, the logic operations of the components are utilized among each other when switching on and off and when taking energy-saving states. The power supply is optimized for a respective operating state of a respective component. The drive element thus regulates a respective power supply of all components, controls the energy status of the infrastructure coupled to the terminal via the arrangement and provides status information regarding the energy state of the individual components of the terminal.
  • In another embodiment, the terminal has a user interface coupled to the controller for interacting with a user.
  • In a further development, the user interface comprises a multifunction button, which is designed at least for switching the terminal on and off. The control unit comprises a unit linked to the multifunction button for controlling the multifunction button.
  • Pressing the multifunction button triggers powering up the terminal and automatically establishing a connection with the virtual data processing arrangement. The connection setup comprises the initiation of an application by the user. Pressing the multifunction button again will break the connection with the device, de-register the user and turn off the device.
  • The multifunction button simplifies the operation of the device, since the entire functionality of the device can be used with the press of a button. Immediate work is possible without waiting time.
  • In one development, the multifunction button comprises at least one sensor, at whose output a sensor signal is provided. This is fed to the unit for controlling the multifunction button.
  • The at least one sensor of the multi-function key, together with the activation, enables an identification of the user.
  • As a result, it is advantageously achieved that, when the terminal is switched on, logging in when establishing the connection with the arrangement is also automated. Consequently, it is possible, for example, to run the booting up of the components of the terminal in parallel with the logging into the infrastructure.
  • The sensor is designed, for example, as a fingerprint sensor, fingerprint sensor. To further improve the authentication of the user further sensors may be provided, for example, a thermal sensor, a motion sensor, a skin resistance sensor, a camera or an RFID sensor.
  • In a further embodiment, the user interface comprises a display element for displaying at least two operating states of the terminal. The controller has a unit for controlling the display element. At the output of a state signal is provided, which is supplied to the display element.
  • Different operating states of the terminal in function of the status signal are displayed on the display element.
  • Advantageously, a user thus essential states of the terminal are clearly represented, which significantly simplifies operation of the terminal.
  • The display element is realized for example on the basis of light emitting diodes, LEDs.
  • In a development, the status signal is generated as a function of an overlay of provided operating states of the terminal.
  • The conditions assumed by the components of the terminal are combined and displayed by the unit for controlling the display element in higher operating states of the terminal.
  • In a further embodiment, the terminal has a peripheral interface coupled to the virtualization interface, which comprises at least one connection to an external device.
  • At least one external device can be connected to the terminal via the peripheral interface. The external device is designed, for example, as a keyboard, mouse or local memory. The peripheral interface is realized in particular as a USB or PS2 interface.
  • In one embodiment, a computer for virtual data processing comprises a processor, a memory coupled to the processor, an interface coupled to the processor for exchanging data, a virtualization layer executable on the processor, and at least one instance of a personal computer executable on the virtualization layer. The at least one instance of a personal computer has a service unit for providing resources for data processing for a virtualization interface of a terminal. In addition, the computer has a protocol conversion unit coupled to the interface for exchanging data.
  • The virtualization layer forms an abstraction layer of the hardware of the computer, ie at least the memory, the processor and the interface for the exchange of data. Thus, the virtualization layer is the basis for the at least one instance of a personal computer, PC. The instance of the personal computer thus has at least the hardware of the computer modeled as a virtual machine as well as an operating system including applications and the desktop of the associated user. With the aid of the service unit, the resources for data processing are provided by the at least one instance of a personal computer of the virtualization interface of the terminal. The exchange of data between the virtualization interface of the terminal and the service unit of the computer via a protocol. The protocol conversion unit realizes a translation of a protocol of the terminal into a protocol of the computer and vice versa.
  • From the point of view of the terminal, the protocol conversion unit advantageously ensures transparency of the protocol used for exchanging data with the computer. This contributes to a substantial simplification in the implementation of the terminal.
  • Currently used protocols include, for example, the Remote Desktop Protocol, RDP, or the ICA protocol.
  • The service unit is also referred to as a connection broker.
  • In a further embodiment, the protocol conversion unit is implemented within the at least one instance of the personal computer.
  • The protocol conversion unit is implemented in software in this case.
  • In a development, the protocol conversion unit is implemented as additional hardware.
  • The protocol conversion unit is implemented here, for example, as an additional plug-in card for the computer.
  • The two implementations of the protocol conversion unit mentioned above can also be combined, in which a part of the functionality of the protocol conversion unit is implemented in hardware and another part as software.
  • In one embodiment, a virtual data processing arrangement comprises a computer, at least one terminal and a communication network suitable for exchanging data between the computer and the at least one terminal.
  • The at least one terminal and the computer are connected via the communication network. The computer provides data processing resources to the terminal. The terminal particularly allows a user to display information as well as user interaction with the computer.
  • With the arrangement, the remote computer and the software are played to the user as a locally usable resource. With the integrated terminal, in connection with the protocol transparency realized in the computer, an optimization and simplification of the virtual data processing is achieved.
  • The communication network is implemented, for example, as Ethernet, powerline LAN or WLAN.
  • In one embodiment, a method for virtual data processing with an arrangement as described above comprises the following steps:
    • - turning on the terminal,
    • Establishing a connection from the terminal to the computer,
    • Display of status information on the terminal,
    • - Use of the terminal for data processing and
    • - Turn off the terminal.
  • Turning on the terminal in this case includes switching on all the components of the terminal, in particular the display, the controller, the virtualization interface, the matching unit, the power supply and the communication unit, in a suitable order. Once connected to the computer, the terminal can be used for data processing. In the entire time between turning on and off the terminal state information is displayed on the display unit of the terminal. Switching off the terminal in particular comprises switching off all components as described above of the terminal in a suitable sequence.
  • In a development, turning on the terminal comprises an identification of a user.
  • This advantageously allows a particularly simple, safe and low-error operation of the terminal.
  • The invention will be explained in more detail using exemplary embodiments with reference to the figures. Functionally or functionally identical functional elements bear the same reference numerals. Insofar as elements correspond in function, their description is not repeated in each of the following figures. Show it:
  • 1 an exemplary embodiment of a terminal according to the proposed principle and
  • 2 an exemplary embodiment of a computer according to the proposed principle.
  • 1 shows an exemplary embodiment of a terminal for operating with a virtual data processing arrangement according to the proposed principle. The terminal includes a controller 1 , a virtualization interface 2 , an ad 3 , an adaptation unit 4 , a split device 5 , a power supply 6 , a user interface 10 and a peripheral interface 15 , The control 1 is with the virtualization interface 2 , the adaptation unit 4 , the split facility 5 , the energy supply 6 as well as the user interface 10 coupled. The split device 5 has a connection 7 for supplying energy and exchanging data. The energy supply 6 is with the split device 5 coupled and provides energy for the above-mentioned components of the terminal, as shown in Figure by the three arrows to the right of the power supply 6 indicated. The control 1 , the virtualization interface 2 , the adjustment unit 4 , the split device 5 , the energy supply 6 , the user interface 10 and the peripheral interface 15 are in a housing of the ad 3 integrated.
  • The control 1 includes a drive element 9 for the energy supply 6 , This is designed to control a power supply of the terminal. So there is a common power management for all components of the terminal.
  • The user interface 10 has a multifunction button 11 and a display element 13 on. The control 1 points one with the multifunction button 11 coupled unit 12 for controlling the multifunction button 11 as well as a unit 14 for controlling the display element 13 on.
  • The ad 3 is designed as LC display. The adaptation unit 4 is also referred to as a scaler.
  • The peripheral interface 15 includes at least one external device connector, such as a keyboard, mouse, or USB device.
  • By pressing the multifunction button 11 the terminal is switched on. About the connection 7 the split device 5 For example, energy and data are supplied to the terminal from a local network, LAN, or via a power network. The split device 5 separates the energy from the data stream. The energy becomes the energy supply 6 supplied, the data stream is the virtualization interface 2 fed. With the energy supplied by the controller 1 turned on the individual components of the terminal in a suitable order. The virtualization interface 2 allows access to computing resources and provides the customization unit 4 a video signal ready. This video signal is available in VGA or DVI format, for example. The adaptation unit 4 converts this format into a format for the display 3 um, for example in LVDS. The video signals are displayed 3 displayed. In addition, on the display element 13 each indicate a current operating state of the terminal, resulting from the superposition of the operating states of the individual components.
  • Advantageously, the terminal uses resources provided by a virtual data processing arrangement. The resources can be bundled centrally and used optimally. Even inhomogeneous resources are transparent to a user. The terminal advantageously has exactly one connection 7 with which it is connected to the arrangement. This significantly simplifies maintenance and installation.
  • In one possible realization is the connection 7 connected to a Power over Ethernet enabled communication network. In another possible realization is the connection 7 coupled with a powerline LAN communication network.
  • In a further embodiment, the multifunction button 11 additionally a fingerprint and a heat sensor. Fingerprint comparison information is stored, for example, in a memory of the terminal. Here, for example, the data is stored only a few users with high resolution. This is particularly advantageous in office or home environments because there are few users working on a terminal. Alternatively, the comparison information for the fingerprint sensor may be stored in the virtual data processing arrangement.
  • In design of the multifunction button 11 with a fingerprint sensor results in the following exemplary sequence when turning on the terminal: A hang-up of the finger triggers a power on 6 out. A connection setup message with the identification number of the terminal is transmitted to the device. Based on this, the instance of a virtual PC that corresponds to a most likely user is prepared and activated on the computer in the device. The most likely user is either a defined standard user or a list of the most frequent users. The fingerprint is compared in the terminal or by means of the computer with the comparative information. The actual user is determined. Subsequently, a login of this user is initiated with the associated password. The already prepared instance of a virtual PC is activated and released.
  • Due to this parallelism results in a significant reduction of the turn-on of the terminal.
  • Switching off the terminal, for example, in two stages: by briefly pressing the multifunction button 11 an unsubscribe sequence is initiated. About the virtualization interface 2 the user is logged off at the computer and resources are released there. For example, the instance of the personal computer is paused on the computer. With long press of the multifunction button 11 an off sequence is initiated. Resources are freed up on the server, for example, the instance of the PC is stopped. Subsequently, depending on the implementation of the drive element in the terminal 9 for the energy supply 6 individual components in a switched off, a low-energy or in a sleep state.

The connection 7a is with the power supply 6 coupled. the interface 8th for wireless data transmission, for example, is designed as a wireless LAN interface. The connection 7a In this case, it is connected to the power supply, ie to a 220 V AC voltage. These too Embodiment is via exactly one port, namely the port 7a , connected to the infrastructure.
  • In one embodiment, the display element comprises 13 For example, a two-color LED, LED. The operating states of the terminal are then coded as follows, for example: When the terminal is switched off, the LED is off; when the terminal is turned on and in connection with the arrangement, the LED flashes green; if the terminal is switched on and connected to the arrangement, the LED lights up permanently green; If an error occurs, the LED lights red. With the help of the control 14 The available states of the individual components are mapped to the states of the terminal described above.
  • The control 14 generates, for example, two signal groups: group 1 contains a summation status signal, which is formed from the superposition of individual status signals of the components; Group 2 includes extended status information.
  • For group 2, for example, eight signals are evaluated as 1 byte. The extended status display of group 2 is then additionally with the multifunction button 11 operable. The extended status information can also be output as a pulse sequence, as a serial color code or as a byte code with the aid of four LEDs.
  • The basis for the overlay, for example, are those of the virtualization interface 2 , the ad 3 and the split device 5 ingestible states. Ingestible states of the split device 5 are: switched on, network active, connected. The virtualization interface 2 can the states: switched on, connection to the server active, take connection to the server aborted. Conditions of the ad 3 are: on, power saving, standby, errors and off.
  • Based on this, the state "terminal switched on and connected to the arrangement" is taken when the split device 5 in the connected state and the virtualization interface 2 in the state "Connection to the server active" and the display 2 either in the state "on" or in the energy-saving state.
  • The switched-off state of the terminal results when the split device 5 or the virtualization interface 2 are not in the switched-on state.
  • The occurrence of an error is indicated when the split device 5 not connected in the state and the terminal is not in the off state.
  • Advantageously, a simple and understandable status display for a user is realized by the display of the superimposed states. The variety of different state information of the individual components is filtered, only the essential states are clearly and clearly represented. Optionally, complete status information is additionally displayed. The number of displayable state information for a respective user group is configurable.
  • For the components of the terminal described above, these logical function units correspond and are not mapped 1: 1 to physical components. In particular, functional units can also be integrated in a physical component, for example the virtualization interface 2 with the adjustment unit 4 ,
